(abstract "Reading and comprehending a codebase is such a time taking endeavor because even in well 
commented codebases all we have at our disposal is a grab bag of facts without a narrative tying them. 
The structure of our programs is still based on the whims of the compiler/interpreter and exploring 
codebases is still a very rigid and manual process.

Scribe is a tool based on the premise that code is data which aims to alleviate some of the problems 
mentioned above by exposing that data to the programmers for documentation and exploration.")
